Max length : 120 cm TL ذكر/ مختلط الجنس; (Ref. 47613); أعلا وزن تم نشرة: 15.0 kg (Ref. 11228); العمر: 22 سنين (Ref. 3627)
الأشواك الظهرية (المجموع) : 11; الأشعة الظهرية الناعمة (المجموع) : 13 - 16; شوكة شرجية: 3; أشعه شرجية لينه: 8. This species is distinguished by the following characters: elongated body with greatest body depth at 2.9-3.7 in SL (for specimens 10-78 cm SL); head length 2.3-2.6 in SL. interorbital width 5.0-6.2 in HL; preopercle with enlarged serrae at angle and a broad shallow notch just above angle; upper edge of operculum straight or somewhat convex; maxilla reaches to or slightly past a vertical at rear edge of eye; upper jaw length 17-20% of SL; midlateral part of lower jaw with 2-3 rows of subequal teeth; gill rakers of first gill arch 8-10 + 14-17; pyloric caeca 50-60; lateral body scales rough, with minute auxiliary scales (body scales ctenoid except for nape, back, thorax, abdomen and above anal-fin base with cycloid scales); lateral-line scales 58-65; lateral-line tubes of anterior scales branched in adults. Colour: head and body tan dorsally, shading to whitish ventrally; numerous small brownish orange or reddish brown spots on head, body, and median fins; body with 5 faint, irregular, oblique, dark bars which bifurcate ventrally (irregular H-shaped bars); back with 3-4 blackish saddles; orange spots become poorly defined and darker with growth (Ref. 39231, 90102).
Inhabit turbid coastal reefs (Ref. 9710) and are often found in brackish water (Ref. 27362) over mud and rubble (Ref. 6390). Solitary (Ref 90102). Juveniles are common in shallow waters of estuaries over sand, mud and gravel and among mangroves (Ref. 6390). Feed on small fishes, shrimps, and crabs. Probably spawn during restricted periods and form aggregations when doing so (Ref. 27352). Females mature at 25 to 30 cm (2 to 3 years old), and sexual transition occurs at 55 to 75 cm (Ref. 39231). Eggs and early larvae are probably pelagic (Ref. 6390). Has been tested in several countries as a potential species for mariculture (Ref. 43448). Caught with hook-and-line, traps, trawls, and lift nets. Common and expensive in markets of the region; sold fresh and kept alive at restaurants in Asian countries (e.g. Hong Kong and Taiwan Province of China) (Ref. 39231).
Pelagic spawner (Ref. 32184).
